I've replied to one or two posts on the forums, I'm still getting used to how they work and where I fit - I'm so used to the BB style! My user name is Teeki.
I just today noticed the mini challenges too, so I'm going to start those this week :)
Reckon I'll get a HRM from ebay too, I found a pretty good Pulse one that I like that's sooo much cheaper than Polar!
